Exam 1 review

General topics for exam 1.  Be sure to review all assigned homework, blog posts and your notes.

You are permitted to have a sheet of notes for this test.  I will NOT give equations.

SI units (m, kg, s) - meanings, definitions

velocity

average vs. instantaneous velocity

acceleration

related motion problems using the formulas

speed of light (c) - approx 300,000,000 m/s

gravitational acceleration (g)

freefall problems

Newton's 3 laws - applications and problems

Kepler's 3 laws - applications and problems

epicycles

Galileo and his telescope

Newton's law of universal gravitation (inverse square law)

weight vs. mass

Weightlessness

center of mass/gravity and torque

Useful equations

Average v = d/t

Vf = a t

d = 0.5 a t^2

F = m a

W = m g

a^3 = P^2

T = F L
